Slab Foundations: Common Issues and Solutions
Understanding Your Slab Foundation: What Every Homeowner Should Know
If your home sits on a concrete slab foundation, you’re among the majority of homeowners—slab foundations are one of the most common types of foundations used in residential construction today. They’re popular because they’re cost-effective, quick to build, and work well in many climates. However, like any part of your home, slab foundations can develop issues over time that need attention. At Hargrave Custom Foundation Repair, we’ve helped countless homeowners understand what’s happening beneath their feet and what it means for their homes. We believe that foundation problems don’t need to be confusing or overwhelming. With some basic knowledge about how slab foundations work and what signs to look for, you can catch problems early and protect your home’s value. A slab foundation is simply a thick layer of concrete poured directly on the ground—no basement, no crawlspace underneath. Your home sits directly on this concrete pad. It’s a straightforward design that works well, but it does mean that any shifting or movement in the soil beneath the slab can directly affect your home. The good news is that most slab foundation issues can be addressed when you understand what’s happening and act quickly. Let’s explore the common problems we see and what you can do about them.
Common Signs of Slab Foundation Problems
The first step in protecting your home is knowing what to watch for. Cracks in your concrete slab, visible on your floors or outside grade beams, are one of the most obvious signs. Small hairline cracks are usually not a concern, but if you can fit a coin into a crack, it deserves professional attention. You might also notice cracks appearing in your drywall or walls inside your home. Uneven or sloping floors are another common indicator. You might notice that a ball rolls across your living room floor or you feel like you’re walking downhill in certain rooms. Doors and windows that stick or don’t close properly can also signal foundation movement, as the shifting foundation changes how the frames align. Water issues are another red flag. If you’re seeing water seeping into your home or damp spots appearing where they weren’t before, your foundation may be allowing moisture to enter. These signs don’t necessarily mean disaster, but they do mean your foundation deserves a professional look.
Why Problems Develop
Understanding what causes slab foundation issues helps you prevent them. Moisture is the primary culprit. Wet soil expands and pushes upward on your slab. Dry soil shrinks and pulls away from your foundation. This constant expansion and contraction puts stress on the concrete and creates movement. Poor drainage around your home makes this worse—if water pools near your foundation instead of flowing away, you’re creating ideal conditions for problems. Tree roots seeking water can also cause problems, as can soil that wasn’t properly compacted before construction. Age also plays a role. Over time, all foundations settle slightly, which is normal. But when settling becomes uneven or excessive, problems develop.
What You Can Do
The most important thing is catching problems early. Small issues are much easier and less expensive to fix than large ones. Keep water away from your foundation by maintaining good drainage. Make sure gutters direct water away from your home, and grade your landscaping so water flows away from the foundation rather than pooling near it. Pay attention to the warning signs listed above. If you notice cracks, uneven floors, sticking doors, or moisture issues, call a professional for an inspection. Delaying foundation repairs typically makes problems worse and more expensive to fix.
When to Call a Professional
